This invention relatesto copy holders, for

use in connection with the operation of type i paper, the pad of paperbeing removable, and

to be used to receive dictation, after which it is placed in the copyholder, and the dictated matter copied by the typist. A further objectis to provide a copy holder in which a single stroke of a lever willadvance a controlled length ofpaper, the length of paper advanced beingvaried by an adj ustment of the stroke of the feed lever.

Afurther object is to provide a copy holder which may be folded,orknocked down, or

collapsed, for packing and shipping.

A further object is to provide a paper holder, or. receptacle, fromwhich the paper is progressively fed by step-by-step stages, as

Other objects will be apparent on reading the specification.

The copy holder is provided with an:enlarged base, 1, upon whichisplaced a type writing machine, with lever 2 at the right side, whereit will be convenient for the typist. The lever moves'within a guide 3,is detachably pivoted at 4 in the hood 65, and is retained retractedbythe spring 5. Uprights 6,

f 7, are pivotally secured at Sand 9 to supports secured to the base 1;The uprights 6 and 5 7 are rigidly braced by the detachable bracket 30(Figs. 1, 3, and 4). Attached to. the lever 2 is the arm 10, (Fig. 4)'which latter ispivotally joined by the member 11 to the verticallyreciprocating bar 13, the upper end of the latter being pivotally joinedto the curved arm 14, and the latter pivotally joined to an extension 15of the paper clamp bar 16. On

the other end of the shaft 12. (Figs. 1 and 2) r is secured an arm 17which is pivotally joined to the vertical reciprocating bar 18, thelatter being pivotally joined to a curved arm 19, resembling the curvedarm 14, and is pivotally joined to an extension 20 of the paper clampbar 16. The curved arms 14 and 19 are the bent up extremities of a facebar 21 (Figs. 1, 4, 6, 7, and 8), the face bar 21 cooperating with thebar 16 to form a normally open clamp, the bar 21 being firmly pressedagainst the inclined face 66 of Fig. 6 of the paper clamp bar 16 by theupward movement of the reciprocating bars 13 and 18 upon ressing thelever 2, the upward movement of ars 13 and 18 clamping the paper andraisin it and the paper clamp bar 16, the outer en s of the latter, 22,of which slide in the slots 23, 23, in the uprights 6 and 7. Figs. 4, 6,and 7 show the bar 16 at the bottom of the slot 23. Fig. 7 shows the bar21 pressing against the clamp bar 16 and engaging the paper 24, while inFig. 8, the face bar 21 and clam l6 and the paper 24 have been raised,the 0 amp 16 is now at the top of the slot 23. Release of the pressureupon the lever 2 disengages the bar 21 from contact with the paper 24and clamp bar 16, separating them, and restoring the bar 21 and clamp 16to the position shown in Figs. 1, 4, and 6 by the retracting spring 5,(Figs. 1, 2, and 4,) which spring engages the lever 2 and upright 7. Thepaper is also independently clamped between the faces of the normallyclosed spring pressed clamp members 25, 26, the bent ends of the member26 being pivotally mounted on the uprights 6, 7, at 27 and the front ofthe member 26 being provided with a suitable handle 28 which permitsseparating the clamp to manually insert the paper 24 therebetween,

' as shown in Figs. 1, 4, and 5.

The portion of the aper from which the dictated matter is copied, isshown at 29, in

Fig. 3. The paper receives a controlled stepby-step feed with eachstroke of the lever 2, the guide 3 which encloses the lever beingprovided with means to limit the stroke of the lever, and thereby limitthe upward movement of the bars 13, 18, thereby limiting and controllingthe feed of the paper 24. The means illustrated to accomplish thecontrolled feed of the paper 24 consists in providing the guide 3 withslot 31, andthe depending cuts 32, 33, 34, and adjustable bolt 35, seeFigs. 1, 2, 4, and 5. In Fig. 4, the bolt 35 is shown in the dependingcut- 34; while in Fig. 5 the bolt 35 is shown in full lines in cut 32,and an additional showing of the bolt 35 in dotted lines is in cut 33.In Fig. 4, with the bolt 35 in the cut 34, the lever 2, on beingpressed, will have a short stroke, and therefore 'will feed the paper 24a short length; with the bolt 35 in the cut 33, as shown in dotted linesin Fig. 5, the lever 2 will have an intermediate stroke, and feed thepaper 24 an intermediate length; with the bolt 35 in the cut 32, asshown in full lines in Figs. 1 and 5, the lower 2 will have a fullstroke and accordingly feed the paper the desired full length. As thepaper 24 is fed through clamps 16 21, it moves over the top and fallsdown at the back, see Fig. 3.

The stenographic note paper preferably used is the kind known as zig-zagfolded strip, folded into a pad, 37, as is shown in Fig. 12. The foldedpaper is used as a pad when receiving dictation, and later is placed inthe folded condition in the paper holding box 38, Figs. 1, 2, 3, 9, and10, with one end of the paper 24 projecting through an opening 40 in thetop of the box; or the paper 24 may be placed in the holder shown inFig. 14. The paper 24 travels from the box 38 bending around the curvededge 44 and passing out the slot 40, and then through the clamps 25, 26,and then through the feed clamps 16, 21, and over the top of themachine, collecting at the back. The paper-holding box 38 is providedwith a hinged lid 41, which is retained closed by the clasps 42, Figs.9, and 10. The upper end 43 of the box is narrow, Figs. 3 and 9, therebyproviding the opening 40 referred to above. The upper edge 43 of the boxextends down inside, and is provided with a curved end, 44, Figs. 3 and9, over which the strip of paper 24 easily travels as it is withdrawnfrom the box by the paper feed clamps. The lid 41 of the box is providedwith a hook 45, which hangs on the cross bar 46, attached to theuprights 6, 7. Figs. 1, 2, 3. As shown in Fig. 10, the lid 41 of the boxis constructed with a grooved edge 48 which engages the edges of thebox, and provides an inside fit for the lid, thereby preventing thefolded paper from getting caught in the joint between the lid and box.

A modified open paper holder 51 is shown in Figs. 14, 15, and 16, andmay be used in place of the box 38, shown in Figs. 1, 2, and 3. Theholder consists of a metal sheet, folded as shown at 52 into a hook bywhich it is supported by the bar 46, and rests against the bar 12. Thelower end of the holder is folded into a channel 53 in which the paper24 rests. WVire guards, or loops, 55, 55, retain the paper in place. Theholder 51 may be riveted to the bar 46 if desired. The operation of thismodification is otherwise as described in connection with Figs. 1, 2,and 3.

An expanded zig-Zag paper pad, 37, consisting of a long folded sheet ofthe paper 24 for receiving the stenographers notes, is shown in Fig. 12.This pad is inserted in the paper holding box 41, on the open type ofholder 51.

In Fig. 13, the copy holder is shown in the knock-down, or collapsedcondition, for ship- 7 ment. To fold the copy holder, the wing nuts 60.Figs. 1, 3, and 4, are removed. the detachable bracket 30 is lifted fromthe bolts 61, which carry the wing nuts, 60, and the To operate the copyholder, the paper pad 37 containing the stenographic notes, is placed inthe paper holder 38, or 51, the end of the paper is then drawn throughthe normally closed clamps 25, 26, and inserted within the normally openfeed clamps 16, 21. The bolt is placed in one of the cuts 32, 83, 34,according to the feed desired, and after copying the notes on theexposed portion 29 of the paper, the lever 2 is depressed, which closesthe clamp bars 16 and 21 against the paper, and also raises the clampsthereby drawing the paper upward the length of the stroke, determined bythe location of the bolt 35. The lever 2 is then released, opening theclamps 16 and 21, leaving the paper in its upward position, and droppingthe bars 13 and 18, and clamps 16 and 21. On repeating the operation,the paper 24 will be fed through the copy holder.
